Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19954, here are decompositions:

5 + 19949 = 19954
17 + 19937 = 19954
41 + 19913 = 19954
101 + 19853 = 19954
113 + 19841 = 19954
191 + 19763 = 19954
227 + 19727 = 19954
257 + 19697 = 19954

Showing the first eight; more decompositions exist.
